[ https://issues.apache.org/jira/browse/FLINK-37435?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17948490#comment-17948490 ]
david radley commented on FLINK-37435:
--------------------------------------
On my busy laptop running IBM Semeru Runtime Open Edition 11.0.24.0 (build 11.0.24+8) I get:
Benchmark Mode Cnt Score Error Units
KryoBenchmark.readKryoBaseline thrpt 25 218.148 ± 9.630 ops/ms
KryoBenchmark.readKryoVersionB thrpt 25 215.178 ± 9.577 ops/ms
KryoBenchmark.readKryoVersionC thrpt 25 238.044 ± 14.186 ops/ms
KryoBenchmark.readKryoVersionD thrpt 25 258.871 ± 9.932 ops/ms
KryoBenchmark.readKryoVersionE thrpt 25 272.074 ± 8.152 ops/ms
KryoBenchmark.readKryoVersionF thrpt 25 509.556 ± 11.247 ops/ms
KryoBenchmark.readKryoVersionG thrpt 25 1689.731 ± 89.401 ops/ms
So only the last 2 make any appreciable difference on my run.
